Auditory-visual coordination in infancy: Some limitations of the preference methodology

“…Nevertheless, we attribute the lack of success in demonstrating sensitivity to simple auditory-visual events to the technique. Humphrey, Tees, and Werker (1979) have shown, using a habituation methodology, that 4-month-olds are very sensitive to the phase relationship between light and sound patterns similar to those employed in the present study. Hence, lack of differential looking cannot be attributed to a lack of sensitivity to such auditoryvisual relationships, even at 4-months-of age.…”

Limitations on input as a basis for neural organization and perceptual development: A preliminary theoretical statement

“…Further, because those stimuli which arc close to the infant, i.e., which are within reach, are most clearly focused, temporal contiguity between visual and tactile stimulation from an object would be promoted. Such continguity might provide a basis for associations between multimodal attributes of an object (Humphrey, Tees, & Werker, 1979;Lawson. 1980), and thereby promote the early appearance of intersensory equivalence (Bryant, Jones, Claxton, & Perkins, 1972;Gottfried, Rose, & Bridger, 1977;Ruff & Kohler, 1978).…”

Matching phonetic information in lips and voice is robust in 4.5-month-old infants

“…In general, infants' ability to pick up "amodal" cues specifying intermodal relations between objects and sounds has been well documented (Bahrick, 1983;1988;Humphrey, Tees, & Werker, 1979;Spelke, 1976;. Amodal information is tied to the structural properties of an action or event but is not specific to a particular sensory modality.…”
